wINDING MACHINE.

Application iled June 3, 1922, Serial No. 565,630. Renewed July 21, 1924.

To all 'whom it may concern.' v Be it known that I, MARTIN B. GROUT, a citizen of the United States of America, and resident of Chicago, county of Cook, and" State of Illinois, have invented certain'new' and useful Improvements in Winding Machines, of which thefollowing is a specification. f i I My invention relates to coil winding machines and has todo more particularly with winding machines of the multipletype in which a plurality of electromagnet coils are wound simultaneously, and an object of my invention is to provide a machine of the above type by which this work can be done in a rap-1d, eflicient and economical manner.

In machines of the present multiple type,

a plurality of helices or coils may be wound simultaneously,and when a'number of coils are wound simultaneously, a single tube-common to all of' them is used and the wire is :wound upon it in separated 'zones or spaces and each sheet of insulating paper between each layer of convolutions of'wire is common to all of the coils so as to mechanically con-` nect all the coils together. `When .the coils have their predetermined number of convolutions, the common tube upon which the coils are simultaneously wound 1s removed and thereafter the plurality of coils may bev separated into indlvidual coils by sawing or cutting throughthe spaces between thev zones of the coils.

The coils wound simultaneously by the multiple winding machine of the above type are built up of a pluralit of layers of wire, each layer having a pre etermined number t of convolutionsfwhile the convolutions` ofwire 'in one layer are-insulated from those in theadjacent layer by means of several layers of interposed paper. The number of convolutions per layer tobe placed upon the tube is gauged by means of suitable gear4 ing mechanism. The travel of the wire fromv left to right, and vvice versa, is controlled by means of suitable mechanism. 7

A sheet of paper common to all the coils is introduced between each successive layer of convolutions and is of such length as to place several layers of paper insulation between each layer of convolutions of wire. rlhe winding machine of the above type, by means of suitable shifting mechanism, travels from left to right, and vice versa, to. wind successive layers of wireon the` core or tube,

and ineans of suitable mechanismy o r manual means asheet of insulating paper 1s Introduced between each layer of convolutions. This sheet of paperl is injected into first turn of winding of the new layer and the second layer of paper is wound into the coil, a space equal to the thickness of the] paper is placed between the first andv second wire turns of the new layer. lShould a third layer-of paper be required, a spaceequal to the thickness of the paper is placed between ther second and third wireturns of the new layer.n It may readily be seen that in addition to the thickness of the three irst wire turns of anew la er the thickness of the papembetweenthe rst and second turns and the second and third turns places the beginning of the fourth wire turn slightly in advance of the predetermined feed which has been set to wind al certain number of-convolutions of ,Wire` per layer. rlhis'slightadvance is lbrought about by the two thicknesses of paper between the firsty and second and second and third wire turns of a new layer. Now, as thel machine operates, the feed arms which .carry the wire across the coil are traveling at a predetermined rate, which rate of travel is regulated by means of suitable gearing, and as the beginning of the fourth turn 1s slightly in. advance of l the. feed arms, it may be readily be seen that the next few turns vwill naturally pile up up at the beginning of a new layer is very objectionable, as it produces a coil which is not uniform in diameter and there isl more or'- less liabilityfor short-circuited turns. ln winding coils manually, the Operator guides the wire by hand and the insertion of the paper at the beginning'of a new layer and the first two or three wire turns of a new layer can be so spaced by the operator as to overcome this piling up of the lirstfewclosely'together, and it is one of the objects ofmy invention to provide means which overcomes this piling up of the first few wire turns of a new layer as described abo-ve.

To overcome and prevent the objectionable feature of the piling up of the turns of wire at the beginning of a new layer, I provide automatic means for automatically advanc ing or shifting the feed arms in the same direction in which the new laver is being v wound upon the rotatable kspindle shaft. The means for shifting the feed arms are adjustable and may be adjusted to shift the arm's to any degree desired, and the spacing `of -the first few wire turns depends upon the adjustment of my compensating device. By means of my compensating device, the turns i are not crowded ahead of the predetermined f layer. the instant a new layer is started and` .rate oftravel of the carrier, because, say for example, that the carrier'is set to place X number of turns of wire per inch to the the first turn is complete, the feed arms are automatically shifted in the same direction -in v/hichthe new layer is being put on, and

- shifted position. Y

for the next few turns the number of turns per inch is reduced the desired or predetermined amount to about Y turns per inch. and this spacing ofthe first few turns of each new layer is brought about by means of the shifting ofthe feed arms in the same direction in which the turns of wire of the layer are being wound on the coil.` When the feed arms are shifted, the carrier feed carryingthe feed arms will notmove until thevlost motion' created b v the shifting of the feed arms is overcome, which will be after the Y number of turns has been placed upon the coil, whereupon the shaft carrying the feed arms will move at the same rate of speed with the spindle shaft, and now places number of turns per inch on the coils until the end of the coil is reached,

when again the shifting mechanism is operaterl and the' compensating means again opcrates to permit the first few turns ofthe new layer to be properlyspaced by. means of the shiftingv of the feed arms.

Another feature -of my .invention is the provision of novel means for accomplishing the operation ofthe compensating vmeans and for overcoming the lost motion producedwhen the feed arms are moved to their For a more complete understanding of my invention, reference may be had tothe ac- Y companying drawings, in which like reference characters in the several views denote like parts. The entire coil winding machine is of considerable size and for the purpose of more clearly illustrating my invention, I

'Referring now more in detail to my invention as illustrated in the accompanyingy drawings, and first describing the main partsy not comprise Aa part of mv invention. and

any suitable power transmission may be used for transmittingr power to the spindle shaft 3.

The spindle shaft 3 is supported at its one end by means of an end plate 5, which is secured to the base plate 2 in any'suitable manner,I and the opening through which the shaft 3 extends serves as a'bearing for theV same. The spindle shaft 3 is also supported intermediate of its end in an end plate. 6 and the opening tln'ough which'it extends serves as a bearing for the same. -The winding shaft 3 has secured at its one end a gear wheel 7, and through the medium of a train of gear wheels 8, 9, 10, 11 and 12 rotary motion is transmitted to a screw shaft 14,

and the ratio of the gear wheels 8 9, 10,11

and 12 to each other determines the number of convolutions per inch which are placed in each layer of wire of the coilsthat are tobe wound. The screw shaft 14 is threaded and is suitably 'journaled in the end plates 5 and 6, and associated with the shaft14- is a.-

gearing device D for purposes as will presently be described. A reciprocating -shaft 15 is provided, which is journaled at its one end in the end plate 5, and at an intermediate point in the end plate 6. An arrnf16 is suitably secured to the shaft 15 and is provided with a. threaded face which is adapted to mesh with the screw of. the screwjshaft" 14. The shaft 15 hasl secured thereto acontrol 'lever 17 andhas associated therewith a guide plate 18 suitably secured tothev base plate 2, and the'movement ofthe. lever 17 rocks the reciprocating shaft 15 to either place the threaded face of the arm 16 in mesh with the threaded shaft 14 or rock the arnr l16 so that its-threaded face is out ofen-r gagement with the screw shaft 14, forpurposesas will presently be described.

Referring now to 2 I illustrate the right-hand portion-of the winding machine, which comprises the-supply device SD supported upon a suitable base 20 upon which are secured the'wire reel or spool racks or brackets RB, of which;.-"I show eight. which indicates that the machine is adapted lto wind eight coils siin'lll-- taneonsly, and as each one' is similar in'con# struction, it is thought that the descriptionv The spool holder RB ol one will'sufiice.

comprises a bracket 21 to which is secured4 a rod 22 extending forward of the bracket 2l andsccured to its free end l sho'wa-QGm i binaion latch and spindle support. 23..'jfgTl1'c spindle 24, which supports the spool of wire' 25` has its one end journaled in the bracketJ 21 and its other end centered in the head 26 of the supportI 23, when. the support is in position. The spindle support 23 is held in position by means of a latch 27, which, when operated, permits the support to be swung downward about its pivot 28 to permit the removal of an empty spool of wire and to permit the )lacing ot a full spool of' wire. An arm 30 1s pivotally supported on the bracket 21, and secured to its free end l show a grooved guide wheel 31.

rl`he reciprocating shaft 15 extends Figs. eend a, in rig,...

through the end plate and lies forward.. of

is journaled 'intlie bearing 32, which is in turn secured -to the base I2. I- fshovr the rey ciprocatingv Vrod. k'15',- equipped with, eight guiding arms 33, each lotwhich has rotatably secured'theretoja'grooved guide wheel 34 which indicatesxthat the machine is y adaptedto wind veight coils simultaneously.

-lVings 35, one on each. side of thebracket 21 and integrally formed therewith, have secured thereto guide'w'ires '36, and slidably mounted on .the saidv .wires is a block 37 carrying a, rotatable guide' wheel 38. The

arm 30 is normally under tension through` vspindle 24, andthe springi39in association with "the arm 43 ofthe lever 42 jcauses the pad 300 to engage disk` 301 and prevents the spool 25 from rotating too fast whentha machine is running, thus keeping the`wire under a constant tension y when being unwound while the machine is .ein use.4

lThe spindle shaft 3, which Vprotrudes through4 its bearing in the end plate 6, has secured thereto a.v winding spindle, 45 by means o a hinge joint 46, the other end 'of lon i the spindle 45 being supported by means ot a suitable block 47, which is secured to the `base 2.."The`block 47 has a clamping member 48 which, `wh en turned, `permits the withdrawal oftheA center 49 so that the winding spindle- 45,4' can be swung forward .through the agency ofthehinge 46' so that a tubefmaygbe vs'lippedfover the winding s indle 4 5 and forced into .they chuck 5() and c amped therein by meansgof a suit-able set screw.`- Next, the'strands of wire 51 are led rearof the winding.. spindle 45, over the grooved wheel'38, vthence under the guide wheel- 31 on the. a-I'1n30, and thence under the guide wheels 34- on the arms 33, which arms 33 are secured to the reciprocating Shaft 15, and tinall to the tube on the winding s indie 45', an attached to suitable termina s in any suitable manner. The block 37 has secured to it a coil spring 251 of a very llight tension, the other end of said spring 251 being suitably secured to a suitable part of the machine, and under normal running conditions of the machine the pull of the wire strands 51 is such as to hold the block 37 against anadjustable stop 253 slidably secured to one of the guide wires 36.

Now, if for any reason the strands 51 become Vfrom the spools25, which are located at the slack, the spring 251 will take up this slack and will at all times hold the strands 51 taut.

Having described in general the essential parts of the multiple winding machine with which my invention is adapted to operate, I will now describe in detall the operation of the control mechanism for causing the operation of the winding machine. I show a lever 52 p by means o the pivot bearing 53 secured to the base 2. The lever 52 is provided with a handle which extends forward of the machine proper, so it may be grasped by the operator. The lever 52 rests between two plates'54 and 55, and tension screws 56 and 57 are provided to exert downward pressure upon the upper plate 54l so as to produce frictional engagement between the faces of the plates 54 and 55, and the faces of the lever 52 so as to hold the lever in either of its positions. A stud 58 is provided on either side of the lever 52 and between the plates 54 and 55 near their ends, which serve as separators between the plates 54 and `and also serve as stops for the lever 52 to limit the movement in its right or left direction. The lever 52 and its associated mechanism control the movement of the reciprocating shaft 15 to the right or left through the agency of a reversible gearing mechanism D and its associated screw shaft 14. The gearing arrangement D comprises a bevel gear 6() rotatably supported upon a suitable bearing 61 which is secured to the base plate 2 and which meshes with a pair of bevel gears 62 and 63 operatively associated with the screw shaft 14. A shaft 64 is provided which is suitably journaled in the end plate 5 to permit its rotation, and keyed to it is the gear wheel 12,y which through its association with the gear train 8, 9, 10, etc., transmits motion to the screw shaft 14. The bevel gear 62 is keyed to the shaft 14 in any suitable manner and thus rotates with it, and being in mesh with the bevel gear 61, motion is transmitted to the said gear 61, and the said bevel ear 61 in turn transmitting motion to the evel gear 63. The screw shaft 14 has a reduced end portion 65 of a size to t in the orifice 66 in. the end of the shaft 64, which serves as one,

bearing for the shaft 14,'the other end being journaled in the end plate 6. The bevel gear 63 is loosely secured to the shaft 14 and suitably collaredy to revent lateral movement of the same on t e shaft 14. A sleeve 67 is provided which is'slidably mounted upon the shaft 14 between the bevel gears 62 and 63 by means of a suitable keyway 68. The plane faces 69 and 70 of the sleeve 67 are toothed, as are the plane faces 7] and 72 ofthe bevel gears 62 and 63, so that when the sleeve 67 is moved to the left its toothed face 69 meshes with the toothed face `71 of the" bevel gear 62, and when moved to the pivoted intermediate of its .ends

vbetween the lever 52 and the slidable sleeve 67 in the form of a rod 73, which has its one end-secured to the head 74 secured to the lever 52, and its other end secured to a yoke 7 5, which spans the sleeve 67. The legs of the yoke 75 are provided with pins 76 which rest in the annular groove 77 in the sleeve 67 to permit the said sleeve 67 to be shifted to the right or left. The yoke 75 is pivotally supported by lmeans of a collar 78 which is securedA to the shaft 79. As illustrated in Fig. 1, I show the lever 52 moved to the right, and through the agency of the rod 73 this movement is transmitted tothe yoke 75, which is in' turn rocked about its pivot to shift the sleeve 67 to the left to cause the toothed face 69 of the sleeve 67 to engage the toothed face 71 of the bevelgear 62. Motion is now transmittedto the sleeve 67 and as the sleeve 67 is slidably keyed to the screw shaft 14, the said screw shaft 14 is rotated and as the arm 16, which is secured to the reciprocating shaft 15, has its screw face in engagement with the thread of the screw shaft 14, the reciprocating shaft 15 is now carried to the right. By means of the gearing train and their pitch ratio to each other, the ratio of the number of revolutions of the' screw shaft 14 tothat of the spindle shaft 3 determines the number of convolutions of wire per inch that are to be placed in each layer of the coil. v

I also provide -a clutch mechanism C which is electrically controlled whereby when the last convolution of wire is put on a layer the clutch mechanism is operated to disengage the power device from the spindle shaft and stop further operation of the machine and permit the operator to actuate the lever 52 and automatically release the clutch to permit the power' drive to again be placed in driving relation with the spindle shaft 3 so that the machineV may start again and cause the reciprocating shaft 15 to move in a reverse direction. The pulley 4 is loose upon the spindle shaft 3 an is provided with an extension 80 whose plane face 81 is toothed. A slidable collar 82 is keyed to the spindle shaft 3 and its left plane face 83 is toothed so that when in mesh with the toothed face of the pulley extension 80, power may be transmitted to the spindle shaft 3. A yoke 85 Vpivotally supported intermediate of its ends by means of a suitable bracket 86 c0- operates with the collar 82 to move it into engagement with the power-driven pulley or out ofengagement `with the power-driven pulley 4. The legs of the yoke 85 which (Meeus span the collar 82 are provided 1with pins 87 which rest inv an annular groove 88 in the collar 82. rl`he arm extension 89 of the yoke 485 has a reduced portion 90 which rests in the bifurcated end of the connecting rod 91, which is pivoted intermediate of its ends by means ofa pivot pin 92 Which is suitably secured to the base 2. The opposite end of the rod 91 is provided with a post 93 which is provided with an orifice of a size to receive a threaded stud 94 which is suitably secured to the core 95 of the solenoid 96. rlhe reciprocating shaft 15 has secured to its left eX- tremity an arm 97 which carries a contactl l5` 98 Which is operativel associated vWith a pair of contacts 99 an 'v1-00. The contacts 99 and 100 are mounted on a plate 101 which is slidably secured to a base 102, which base is in turn secured to the base 2. The plate -101 upon which the contacts 99 and 100 are securedis slidably supported and may be moved to the right or left ashort distance for purposes as W1ll now be described. Assuming that the reciprocating shaft 15 is that t-he last turn of Wire is placed on the layer that the machine 'is Winding in a righty to leftv direction, the contact98 of the arm 97 engages the contact 99 on the slidable plate 101. rllhis closure of contacts 98 and 99 establishes an energizing circuit for the solenoid 96 to attract its core 95, and due to the connection between thelcore 95 land the rod 91, the said rod 91 is moved about its pivot 92 to cause the end which engages the armA 89 of the yoke 85 to rotate the said yoke 95 about its pivot 105, and due to the connection Ibetween the collar 82 and the yoke y85, the said collar 82 ismoved to the right to disengage the power-driven pullely 4,' th-us stoppmg further Winding of the machine-as l the pulley 4 is loose on the shaft 3. .The

operator now grasps the lever 52 and movesj it to the right to place it in the position shown in Fig. 1. This vmovement of the lever 52 moves the rod 73 to the right and rotates the yoke 75 about its pivot to move the sleeve 67 to the left, causing the toothed face 70`of thefsleeve 67 to disengage the 'cause the toothed face 69 of the sleeve 67to engage the toothed face 71 of the bevel gear' 62. A rod 106 is provided which has' its one end secured to the yoke 75 and its other end 5 secured to a block 107 which., is mounted on the sliding plate 101. Thus, when the yoke 75 is rotated about its pivot 79 when the lever 52 is actuated, the movement of the yoke 75 moves the rod 106 to the left, and as the rod 106 is connected to the plate 101, the said plate isalso moved 'to the left, opening the contacts 98 and 99. This opening of contacts 98 and 99 opens the energizing circuit of the solenoid 96, and it releases its core l95, allowingthe arm 91 to again rotate traveling from right to left, at the instant toothed face 72 of the bevelgear 63. and.

about its pivot 92 and again permit the toothed face 83 of the sleeve 82 to again engage the toothed face 81 of the extension 80 of the power-driven pulley 4, and this is the position of the. mechanism as'illustrated in Fig. 1 and places the machine in condition to place a layer on the coils from left to right. To start the machine the operator actuates a suitable starting pedal and as the clutch is thrown in a position the shaft 3 is again connected to the power-driven pulley 4 and `motion is transmitted to the screw-shaft 3 in a direction to cause the reciprocating shaft 15 to travel from left to right to place another layer of Wire in the core.

rIhe description up to this point gives in detail the shifting mechanism for reversing the ltravel of the mechanism to place succes-- sive layers of wire on the coil. l will now describe in detail the arrangement of the compensating mechanism of my invention for preventing the piling up of the lirst few turns of Wirefat the beginning of a new layer being wound upon the coil.

F or associating Y the guide' arms 33 with the reciprocating shaft 15 so that the same may travel with the said shaft 15, ll provide a sup .orting member or rack 200, 1Which is provi ed with a channel 201 to receive the guide arms 33. rlhe arms 33 are properly spaced from each other and'pivotally mounted in said channel 201 by means of pivotpins 202, which extend through suitable oriices in the arms 33 and which are secured in orifices provided in the sides of the rack- 201 by a drive fit. The member 200 is securely clamped upon the shaft 15 in any suitable manner to prevent movement of the same on the said shaft. To the left end portion lof the member 200 is secured the com- Vpelisating means of my invention for shifting the guide arms 33 and which comprises an L-shaped member 205 Which is pivotally supported on the member 200 by a pivotv pin 206 Whose one threaded "end has screwthreaded engagement with a suitable tapped orifice in the member 200, and which pin has its other end threaded for receiving a nut. rllo prevent the displacement of the l.-shaped member 205,.a Z-shaped 4member 207 is provided which is secured to the mem- `ber 200 by a screw 20S-which passes through a suitable orifice in the member 207 and has screw-threaded engagement with an orifice in the member 200; the other end of the member 207 has an orifice for receiving the threaded end of the pivot pin 206, and to maintain the member 207 in this position a nut 209V is provided to engage the'threaded end portion of the pivot pin 206. A slot 210 is provided in the leg 211 of the member 205 and an adjustable set screw 212 isprovide which engages a suitable tapped orifice in the leg 211, which permits one end of an adjustable screw stop 212 to protrude into 130 the slot 210 and coo crate with a pin 219.k A secured tothe arm to limit the pivotal movement of the member 205 for purposes as Will be presently described. A lock nut b213 is provided for maintainingy the said screw 212 in its. adjusted position. The other leg ofl the L-shaped member 205 has its free end bifurcated and is of a size to receive a 'member 215 provided with projections 216 integrally formed with its .one

end and having its other end pivotally `sup-v orted in# the biturcated end of the mem- Eer 205 by means of the bolt 214. vThe first guide arm 33 to the left will be termed the master -arm MA, since through its movement the movement of the other guide arms 33 is controlled, due to the fact that all of thereto by means of its threaded end, which has screw-threaded engagement with an oritice in the varm MA, said pin 219 being arranged so that it rests the slot 210 inthe member 205, -and cooperates withthe ad-ustable screwstopy 212, the purpose 'oi w ich will hereinafter be ointed'out. The arm MA is provided wit a pair of integrally formed Wings 220 and 221, each of which is provided with a threaded orifice, which are.

adapted to receive the adjustable stop screws 222 and 223. Lock nuts 224 and 225 are provided for the stop screws 222 and 223 for the usual well-known purposes. The adjustable set screws 222 and 223 regulate the extent of the pivotal movement of the arm MA .to the right or left for purposes as will be presently described. To the right end portion of the rack 200 associate a frictional device F which comprises a U-shaped member 250 which is secured to a supporting block 251 secured to the base 2 by any suitable means. The U- shaped .member 250 has integrallyl formed ears 252 intermediate yot" its ends, between which a rod 253 is pivotally su ported by means of a pin 254v enga ing ori ces in said ears 252 and rod 253. o the back of the member 250 is secured a pair of plates 255 by means of screws engaging suitable orifices in said plates 255 and member 250. Between the plates 255 a member 256 is pivotally mounted at its one end by means of a pivot in 257l and in the other end an vorice 25 is provided through which the rod asses. To the bottom surface of the mem er 256 is secured'by means of rivets or screws a frictional member 258, which maybe of leather, or any substance which will give a frictional effect, and to the U- l shaped member 250 is also secured a simivlar'frictional member 259 by means of suitable rivets or screws. A 'flat sliding plate 269 is slidably supported between the friction plates 258 and 259 and has-secured to vits one end an angular strip 27 0. The inner surfaces of ,thestrip 270 and plate 269 are slightly hollowed outtoreceive a ball 271,

-to provide a ball and socket joint, the 'said ball 271 having a` connecting knuckle 272 secured thereto. The plate 269 rests between the legs of the vU-shaped member 250 and also operatively engages the faces 273 and 274 of the frictional members 258 and 259. In order to obtain a definite frictional engagement between the plate 269 and members 258 and 259, a coil sprin'fr 275 is provided which is placed over the Tree end of the rod 253 and has its one end bearing against the upper face of the 'member 256 and its other end bearing against the bottom face of a nut 276 which has screwthreaded engagement with the rod 253. Bv this arrangement the nut 276 may be moved downward toincrease the tension of the spring 27 5, therebyv forcing the members 25S and 259 and plate 269 into closer en agement with each other. A cylindricalg rod 260 is secured in an oriice of the member 256l by means of a drive 4fit, said rod ext.

tending parallel to the guide arm carrying member 200. A U-shaped plate 261 having a hook-shaped member 262 secured thereto by suitable means is clamped to the arm carrying member 200 by means of theset screw 264, which engages an orifice in the said plate 261. The hooked portion. of the member 262 is adapted to receive the rod 260, the purpose of' which will presently be described. The L-shaped member 205 and the frictional means F are now operatively connected together by means of a connecting rod 265, which has its one end connected to block 266, which is pivotally mounted between the ears 216 of the member 215 by means of a pin 267 extending through suitable orifices in said ears 216 and said connecting block 266; the other end of said rod 265 being connected to the connecting knuckle 272 by a threaded engagement.

Having described the apparatus which comprises my compensating device, I will now describe in detail its operation in connection with the winding of a coil. When the lever 52 has been moved to the position shown in Fig. 1, which is the position of the lever 52 when the reciprocating shaft l5 starts travel from left to right, and tho clutch pedal is operated, the shaft l5 will be moved from left to right by the power mechanism. Assuming, for the sake of a clear explanation of the operation of the machine, that the ratio of the train of gearing lia of the machine is arranged to wind a layer of wire at the rate of 16.9-turns of wire per inch on the coil and that threeturnsl of insulating paper are to be placed between each newA layer of wire. /`l\low',`the instant that the operator operates the lclutch'pedal to app ly power to the power drive pulley 4, mo-

tion is transmitted to the screw shaft 14g" through'the train of gearing and the gear-k ing mechanism D, and as the larm 16 of the reciprocating shaft is in engagement with the screw shaft 14, the Vshaft starts travelhto. the right. The instantthe powerisapplied say, at the rate of fifty turns per'inc duo` to thedrive pulley 4 the shaft3 begins to ro.- tate to place the turns ofwire upon the coil andvto wind'l the paper intothe l coil, Due.. to thek adjustment -of the compensating "device, the first turn onturn and a half --of wire may be put on atthe rate of 169 turns per inch, and the next few turns may. be ut injto the adjustment ofthe compensating. derice. When the shaft 3 vbegins torotateand at the same time the shaftl 15, to lwhich the arm carrying member 200 is secured, (and.

which travels with saidfshaft 15, begins. to

travel to the4 right, the number' of turns'ofwire will be put on at the rate of 169 turns per inch and at the same time the member 205 of the compensating device will be .ro-f

tated'about its pivot-206 tothe right, due tof.A 'the pressure exerted 'upon it by the'movef ment of the vshaft 15 tothe right,` and'also due to the friction device F- which gripsy theJ plate 269 between thefriction members 2.58 and 259, the vfriction devicebeing of suf,-y

ficient strength at this` time to vprevent they lateral movement of the latel269, to which.

is connected one end o the, member 205 4throughl the mediumjof 4the connecting rod? Just as soon as lthe member 205 has 265. rotated about its pivot far enough so thatI the left-side lofv the slot=210 engages the piu'y 219 ofthe master arm MA, which we have.

assumed 'l will be immediately after the completion of the firstv turn or turn kand a half of wire and paper upon the coil, the master., arm MA will rotate about its pivot202 to'. .the right tospace the `nent few turns of wire at the I lateof'fifty turns per inch until Athe stopxserew- 223 engages the bottom of the channel 201 in the member 200, which will 'prevent the further rotation'of the master arm MA and 'member l205;'to 'the right,

Elate 269 by the friction device. is overcome y the lateral pressure exerted-upon the manner vand at the same` rate `of turns of wire'periinch as that describedl abovev since 4the guide arms 33 are connected "to the mas` ter` arm MAby the connecting bar 217 and the said arms 33 move simultaneously in the same 'directioninj'which the master .arm MAmoves. Now, when #the shaft 15 carrying thel guide" arms and `33 and the compensatin .device has moved to the right its entire istance,`alnew sheet of paper isplaeed ready .tc1"bewound into the coil. The operator, after vpla'cin the edge of `the paper upon the'coilfand g beneath the strands of Vwire 51, moves the `lever 5 2 'to the left and then yoperates -tjhe .-clutch pedal to apply power to the vpower drive pulley 4 for the same lpurpose just .described above. The shaft 15 will now't'ravel from right to left and the `member 205 will rotate about its pivot 206 due tothe'pressure exerted upon,

left far enough.l so that the ,rightside 'of the i '1t by the' shaft 15, and due to the non-move- "slot`210 enga es the pin 219 onthe master l.

arm MA, an' up; until thev side (,f said slot orgfirst anda halfturn as before described, .l l o y the mastera-rm MA will be rotated about lits 210'does engagesaid pin-219, the turns of y pivt 202 mths left until' the top Screw 222. i

engages the bottom of the channel 201 of the ymem er 200, and during this rotation of the arm the-turns of wire will be wound at the rate-of` fifty/,turns per vinch. When the l'channel 201 the master arm is prevented l'from furthery rotation to theleft and the turns kof .wire willagainbe woundk at the' rate of 169 tui-ns'per inch, and the pressure now :exerted upon*'the."membe12'05 by the shaftl overcomes fthe grip ofthe` friction device, whereb. 'the plate 269 slides between the "friction 1p ates 2,58 and 259 to the left with Ythe shaft 15.' VVhen'the shaft has traveled to the left itsentire distance, the 'operator insert'sanother sheet of paper and operates the lever 52 and, clutch pedal to y'start' the travel of the |`shaft 15 to the right, whereupon the pressure exerted upon the :i

as described above. t

Shouldfthe-'operatordesire to .space the tunrs of wire manually, as for instance 'at the beginning of a new coil or upon the coin-` pletion of a coil, she may do so by operating the lever17 connected to the shaft 15, which will cause the shaft 15 to rock in ,its bearing to cause the `disengagement ofthe varm 16 and threaded shaft A14 and to release' the pressure exerted upon the'plate 269 by the friction device F; Whenthe lever 17 is opst'op screw 222k engages the bottom of the' Vao ` travel of the shaft 15 so 'that the turnsof' 200 moves with it.

erated the shaft 15 is rocked downward, causing the hook member 262 to engagethc rod-260 connected to the plate 256 to cause said plate 256 to raise upward against the tension of the said spring 275, whereby the plate 269 is released and free to move, thus permitting the shaft 15 to be freely moved to the right or left.

It may thus be seen that the instant that thc spindle shaft 45 rotates, the shaft 15 also starts moving from left to right. The member 200 is secured to the shaft 15 and' as it also carries the pivotally supported arms 33, thel said arms also travel from left to right. rlhe member 205 is pivotally supported upon the member 200 and the instant. the shaft 15 starts its travel the member The member 205 is op'` eratively associated with the plate 269 through the medium of the connecting rod 265, and due to thel friction means F through which the'plate 269 extends, ylateral move@` ment of the plate 26S)- is prevented. The movement of the'member 200 continues, and this friction, which prevents the movement of plate 269, causes the member 205 to rotate about Yits pivot through' the agency of the connecting link 265, until the face 302y of the slotk 211 engages the stud 219 onthe arm. During the movement of the member 205 the arm does not rotate aboutit-s pivotand the first turn of wire is placed on the new layer at` a predetermined rate'. The continued movement vof the member 200 causes further rotation of the member '205 about its pivot 206, but as the face 302 of p the slot 211 now engages the stud 219, the

master arm MA is rocked about its pivot and moved tothe right. The movement of the member 205 is slight, but due to the fact that the arm MA is pivoted at the point 202 and movement is transmitted thereto through the agency ofthe member 205 'and stud219,

this slight movement of member205 is mulf tiplied due to the difference of the pivot centers of the member 205 and arm MA, and this movement of the arm MA is multiplied at its free end and causes the next few turns to be spaced apart, and when the screw Astop 222 engages the bottom of channel 201, furv ther movement of member 205 and arm MA is prevented and the turns are againx'placed on at apredeterminedrate. This shifting of arm 'MA'is also'transmitted to the seven other arms 33, due to the connecting link217. j y

By having the member 2 05 and-[master arm MA pivoted at different centers and associated y means of the slot 210 and pin 219, I am able to advance or shift the guide arms of the feeding device to the' left or right` depending `on the direction of the wire may be properlyv spaced and `so that thevfeeding device will not lag behind the lirst few turnsof wire due to the convolutions of paper bein wound into the coil between said turns o wire, thus avoiding any crossing or piling up of turns of wire. Furthermore, b the ad]ustment of the set screw 212'in the s ot 210, I am able to decrease or increase the predetermined number of turns -of Wire per inch at the beginning of eacn new layer before the guide arms are shifted, and by means of the adjustable stop screws 222 and 223 I am able to increase or decrease the amount of movementof the guide arms, which will determine the number of turns of wire per inch during the shifting ofsaid guide arms. v i

While I have described my invention in connection with a particular type of multiple winding machine, vI do not wish to limit the application of my vinvention to a particular type of winding machine, as my invention is applicable to other types of winding machines.v Furthermore, it is to be understood thatmy device is ad]ustable to put on different' numbers ofl turns of wire per inch andis not to be limited to 169 or 50 turns per inch, as these numbers were used only for the pur ose of explanation. I also do not wish to e limited to the exact structure as shown, as changes and modifications will readily suggest themselves and I, therefore, aimto cover all such changes and modifications as come vwithin the spirit and scope of the ap ended claims.
